Thanks, RadioKid! This is at least something than nothing. This happened at the Tokyo airport, and If we assume that I was talking to a baggage-handling girl worker, then maybe she meant "flying baggage" by writing the FB (or "F" could mean another adjective in regard to baggage) because she didn't speak English. Maybe "FB" is an airport coatroom in Japanese? How'd you think?
And secondly, RadioKid-San, could you please tell me what the bottle label says, especially the numbers 50, 100, 17, 18. Give me all essential information, including taste. What's the alcohol content? I am attaching the photo. Thanks, bro. Siberia won't forget ya.
